c-ares is an asynchronous resolver library. When cross-compiling c-ares and
using the autotools build system, CARES_RANDOM_FILE will not be set, as
seen when cross compiling aarch64 android. This will downgrade to using
rand() as a fallback which could allow an attacker to take advantage of the
lack of entropy by not using a CSPRNG. This issue was patched in version
1.19.1.
